Frank Lloyd Wright’s Fallingwater Has a New, Waterproof Roof

The Western Pennsylvania Conservancy has completed a comprehensive three-year, $7 million restoration of Frank Lloyd Wright’s architectural masterpiece, Fallingwater. The project focused on critical structural vulnerabilities, including moisture degradation of interior finishes, leaking windows and doors, and the installation of a new waterproof roof. Experts addressed specific design flaws inherent to Wright’s original 1935 construction, such as the lack of through-wall flashing and the use of river pebbles in concrete aggregate, which had exacerbated the building's battle against the elements.
